Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus for blocking an operating element of an automatic transmission of a vehicle, a method for operating the apparatus of the above type, and a shift device for shifting an automatic transmission of a vehicle OPERATING SUCHE DEVICE AND SWITCHING DEVICE FOR SWITCHING AN AUTOMATIC TRANSMISSION OF A VEHICLE}

The present invention relates to an apparatus for blocking an operating element of an automatic transmission of a vehicle, a method for operating the apparatus of the above type, and a transmission for shifting the automatic transmission of a vehicle.

In the field of vehicles, for example, a multi-stable shift position such as "P "," R ", " N ", "D ", and so-called" Shift- ) "Function, and the shift operating portion is provided with a so-called" AutoP "function, that is, a transmission-side automatic parking lock function. In the shift lock function, the shift lever is blocked and released again after the brake is actuated. Normally, the shift lock function is implemented by an actuator, for example, an electromagnet. In AutoP, when a parking lock is input to the transmission, the P-position is immediately input to the shift actuator by the actuator again.

DE 10 2006 007 600 A1 discloses a rotary actuator for electrical or electronic equipment in a vehicle.

From this background, the present invention provides an improved apparatus for blocking an operating element of an automatic transmission of a vehicle, an improved method for operating an apparatus for blocking an operating element of an automatic transmission of a vehicle, And to provide an improved transmission for a vehicle.

The configuration of the return ring having the control contour in the automatic transmission transmission of the vehicle is such that the blocking or blocking of the operating element of the transmission, which is associated with or engageable with the return ring, Release. In a further function, the return ring can be configured to return from the AutoP function of the operating element to the parking position.

According to the concept described herein for expansion of the return ring for the AutoP function via the control contour for the blocking element of the shift lock function, the functions can be optimally integrated in terms of cost and packaging. Further, the additional function of disengaging the locking portion of the locking comb of the transmission may also be incorporated.

In particular, only a single actuator or electric motor is required for the implementation of the functions described herein.

An apparatus for blocking an operating element of an automatic transmission of a vehicle includes a locking comb having a blocking contour supported rotatably and directly engageable with the operating element; In a first position, is arranged outside the blocking contour to release the locking comb in order to allow for the adjustment movement of the operating element, and in the second position to be arranged in the blocking contour to fix the locking comb for blocking of the operating element A blocking element configured; An actuating ring rotatably supported for guidance of the blocking element between a first position and a second position, said actuating ring having a control contour; .

The device may be part of a vehicle's equipment or equipment. The vehicle may be a road vehicle such as a passenger car or a commercial vehicle. The operating element may be, for example, a ring or a shift lever of an automatic transmission that can be manually operated by a vehicle driver to set a different speed change stage of the automatic transmission. For example, the driver can adjust the operating element through rotation or shifting between, for example, P for parking, D for driving, R for reverse travel, N for shifting the transmission to idling. The locking combs may be formed in a circular shape, in particular in the form of a rotary knob, in the construction of the operating element, and may be arranged parallel to the plane of rotation of the operating element. The locking comb is used to transmit the operation of the operating element to the automatic transmission and can be combined with the operating element through a mechanical connecting element so that the movement of the operating element causes a constant movement or rotation of the locking comb extending in parallel . The locking comb features a plurality of raised portions arranged in a comb shape and can include an annular locking contour through which the movement of the operating element can be optimally shifted to the shifting position of the automatic transmission. The blocking contour may be formed in a recessed shape that is preferably dimensioned between raised portions of the locking comb. The blocking element may be positionally fixed relative to the rotational movement of the locking comb and arranged in the device, for example in the support structure of the housing or device. The blocking element can be configured, for example, in a cubic shape, and can be arranged in the device such that the blocking element can be moved along the longitudinal axis of the cube between the first and second positions. The blocking element may be configured to be further away from the center of the circular locking comb at the first position than at the second position. The arrangement of the blocking elements which are positionally fixed with respect to the rotational movement of the locking comb can be realized through the coupling of the blocking elements to the inner side of the housing of the device, for example. The actuation ring may be formed as a disk having a central bore. The actuating ring may be arranged in the device in parallel with the locking comb. The control contour may be formed and configured in one piece with the actuating ring to move along the blocking element for movement of the blocking element between the first position and the second position. When the blocking element is engaged into the blocking contour at the second position, the locking comb and the actuating element are blocked against rotational movement. Thus, the operating element for the operation by the driver can be blocked. By moving the blocking element to the first position, the locking comb and the operating element can be moved again. Thereby, the driver can operate the automatic transmission again through the operating element.

According to one embodiment of the device, the blocking contour may be formed in the locking comb by a recess, and the contour of the recess may correspond to the contour of the blocking element. Thus, in an embodiment of the blocking element as a square, correspondingly the recess may comprise a right-angled U-shape. In this case, the size of the recess is slightly larger than the size of the blocking element, so that the blocking element can be moved into or out of the recess without tilting. With this embodiment, the blocking element can be moved between the first position and the second position particularly fast and with little risk of tilting.

For example, the control contour may be formed by a groove extending in the working ring. The grooves approach the outer contour of the first groove section closer to the outer contour than the inner contour of the working ring, for example in the second groove section, curved toward the inner contour of the working ring. In this case, the first groove section may be configured such that the blocking element is guided to the first position. The second groove section may be configured such that the blocking element is guided from the first position to the second position. The grooves may be formed along the annular extension of the working ring. The grooves may be processed completely through the working ring or removed from the surface of the working ring facing the blocking element, only in the form of an indent. The control contour formed as a groove is simply manufactured and particularly easy to manage.

For example, the blocking element may include an extension on one side facing the control contour, and the extension may be configured to engage the control contour for guidance of the blocking element. The extension may be formed as a single piece with the blocking element. With the extension, the blocking element can be moved with a particularly precise and precisely low energy consumption. It is also possible simply to prevent the blocking element from inadvertently exiting from the control contour during the form-fitting connection of the extension and the control contour.

Wherein the locking comb is arranged between the actuating ring and the actuating element and the blocking element is arranged radially with respect to the locking comb and actuating ring and the blocking element is arranged radially between the first position and the second position The device may be configured to be configured to move in the first direction. Due to the sandwich arrangement of the locking comb between the actuating ring and the actuating element, the locking comb meets the task of converting the rotation of the actuating ring into blocking or unblocking of the actuating element, in a particularly functional and space saving manner . The radial arrangement of the blocking elements with respect to the locking comb is particularly functional in such a way that the locking or releasing of the locking comb is performed through the blocking element transversely to the direction of rotation of the locking comb.

Further, according to another embodiment, the apparatus may include a locking pin configured to be coupled to a locking portion of the locking comb, e.g., a locking contour, in a first position. Thereby, the locking function can be realized by the cooperation of the locking portion of the locking comb and the locking pin located at the first position. The operating element can only be moved from a predetermined position to another position by overcoming the locking pin. When the locking pin is located in the first position, the locking comb can only be moved away, for example, only through the locking pin, during operation of the operating element via the driver. In addition, the locking pin is configured to release the locking comb, i. E., To stop the locking function, for rotational movement that is free to operate in the second position. In the second position, the locking pin may be located outside the locking contour of the locking comb. Also, the locking comb may include a stop element and the rotatably supported actuating ring may include a control cam and a nose. In this case, the control cam can be configured to move the locking pin from the first position to the second position during the rotational movement of the actuating ring, the nose interlocking the stop element during the rotational movement of the actuating ring, With the detour of the locking function, it can be configured to adjust the operating element to the parking position without having to overcome the locking. Movement of the locking pin to the second position is carried out against the elastic force of the spring element which exerts a load on the locking pin. The stop element can include a stop surface that can be arranged between the rising portions of the locking comb and extends horizontally with respect to the rotational plane of the locking comb. The control cam of the actuating ring may be formed in the outer contour of the actuating ring in the form of a rounded projection while the nose of the actuating ring may be formed in the inner contour of the actuating ring. The nose may in particular comprise a stop for the stop surface of the stop element and a corresponding surface for the formation of the engagement point between the working ring and the locking comb. The control cam and nose can be formed in one piece with the actuating ring. This embodiment enables a desirable combination of shift lock function through the return of the operating element in the so-called AutoP function and the simple change of the rotational direction of the operating ring. The return of the operating element can be achieved by rotation of the operating ring in the rotational direction, while the shift lock function can be activated through the return rotation of the operating ring in the rotational direction opposite to the rotational direction.

In particular, the control contour may extend within the region of the control cam in the actuating ring. Therefore, a combination of the AutoP function and the shift lock can be implemented particularly effectively.

The device may also include a coupling element associated with the actuator. The coupling element can be configured to transmit the torque of the actuator onto the actuating ring for the generation of rotational motion of the actuating ring. The coupling elements can be configured as a toothed wheel that can be arranged adjacent to the working ring, for example in a parallel plane, and can be coupled directly or indirectly with the working ring. The actuator may be, for example, an electric motor. By this embodiment, in a simple and inexpensive manner, the movement of the electric motor is transmitted to the first rotational movement of the operating ring in the first rotational direction and to the second rotational direction of the operating ring in the second rotational direction . ≪ / RTI >

A shift device for shifting an automatic transmission of a vehicle includes an operating element configured to be adjusted between a parking position or an idle position of the automatic transmission and one or more running positions of the automatic transmission, and an operating element according to any one of the claims Wherein the locking comb of the device is directly coupled to the operating element.

The operating element may be implemented or configured as a rotary knob, for example, so as to be operated by the driver of the vehicle. The driver can move the vehicle in two opposite rotational directions to set the corresponding speed change stage in the automatic transmission of the vehicle to the parking position "P ", the driving position" D ", the backward travel position "R ", the idling position & The operating element can be rotated. The actuating element can be combined with the device such that the position of the actuating ring or actuating ring has a direct impact on the rotatability of the actuating element. Blocking of the operating element via the operating ring can be realized by the driver of the vehicle, for example, when the operating element is at the "P" position or the "N" position, for example, in particular when the brake of the vehicle is deactivated. Activation of the brake by the driver causes the actuating ring to unblock the actuating element and the driver can rotate or adjust the actuating element, for example, from the "P" position to the "D" position. For example, the operating element can be inserted on the device and / or can be connected to the locking comb or other connecting device of the device via a form-fitting or also a press-fit or material-mating connection.

1 schematically shows a vehicle 100 having a transmission 102 according to an embodiment of the present invention. The transmission 102 is configured for shifting of the automatic transmission 104 of the vehicle 100 and assembled from the apparatus 108 for blocking the operating element 106 and the operating element 106. [ The device 108 is coupled with the operating element 106.

Through operation of the operating element 106, the driver can select a desired shift state of the automatic transmission 104, for example, P for parking, D for traveling, R for reverse travel and neutral position of the transmission 104 N or 0 can be set. When the driver does not activate the brake of the vehicle 100 at the transmission position P or N, for example, via the device 108, the operating element 106 may be blocked for operation by the driver. As soon as the driver operates the brakes with the feet, the device 108 releases the operating element 106 again and the operator can set the desired gear stage. The transmission 102 receives information on the actual operation or non-operation of the brake via the controller of the vehicle 100, for example, associated with the transmission 102. [

To this end, the device 108 comprises a locking comb 110 having a blocking contour (not shown) coupled directly and rotatably with the operating element 106, a blocking element 112, And a control contour (not shown) rotatably supported for guiding the blocking element 112 between a first position and a second position. The blocking element 112 is arranged outside the locking comb 110 at the first position and within the blocking contour of the locking comb 110 at the second position so that the locking element 110, Lt; RTI ID = 0.0 > 106 < / RTI >

Fig. 2 shows a detailed view of an embodiment of the transmission 102 of Fig. For improved overview, the transmission 102 is shown in an exploded view in Fig. The operating element 106 coupled with the device 108 is configured to be operated by a driver of the vehicle in which the transmission 102 is installed in order to set a different speed change stage of the automatic transmission of the vehicle combined with the speed change device 102 do. In the embodiment of the transmission 102 shown in Fig. 2, the operating element 106 is configured as a rotary knob and correspondingly includes a cylindrical shape. In accordance with the configuration as the rotary knob, the shifting process of the transmission 102 is executed through the rotation of the operating element 106. [ To this end, the section of the cylindrical wall of the operating element 106 comprises a grooved surface for improved grip. The purpose of the described device 108 according to the present invention is to provide a shift lock function, that is to say, when the transmission of the vehicle is in the parking position or idling, when the vehicle brake is deactivated, And to release the blocking by activation of the vehicle brake. According to the embodiment, the shift lever or the operating element 106 may be blocked at a position other than the first shift position P, N. [

2, the locking comb 110 is arranged between the operating element 106 and the actuating ring 114. As shown in Fig. The actuating element 106, the locking comb 110 and the actuating ring 144 are arranged in a parallel plane. The locking comb 110 is directly coupled to the operating element 106 and includes a cylindrical or ring shape and is slightly smaller at the periphery than the operating element 106. The locking comb 110 is rotatably supported within the apparatus 108. The locking contour of the locking comb 110, which is clearly visible in FIG. 2, allows precise setting of the speed change stage to the operating element 106.

Here, the blocking element 112 is comprised of a long cube and arranged radially with respect to the locking comb 110 relative to its longitudinal axis and oriented toward the blocking contour 200 of the rotary knob 106. The blocking element 112 is configured to be arranged outside the blocking contour 200 in the first position so that the locking comb 110 can be rotated in two directions without interruption. The blocking element 112 is configured to be coupled into the blocking contour 200 in a second position to secure the locking comb 110. The blocking element 200 is positionally fixed relative to the rotational movement of the locking comb 110 and is arranged within the device 108. That is, the blocking element can be moved radially with respect to the locking comb, but can not be moved along the periphery of the locking comb. The blocking contour 200 is formed in the locking comb 110 through a recess of a concave-convex type and the recess is oriented toward the working ring 114 and the blocking contour 112. In this configuration, the blocking contour 200 is optimally suited for receiving the cubic blocking element 112. The recess forming the blocking contour 200 may be less rigid than the blocking element 112 because the blocking element 112 may move into and out of the blocking contour 200 without tilting. Lt; RTI ID = 0.0 > approximately < / RTI >

The movement of the blocking element 200 between the first and second positions is implemented by a control contour 202 arranged in the actuating ring 114. Similarly, the rotatably supported actuating ring 114 is arranged in a plane adjacent to the locking comb 110 and parallel to the plane of the locking comb 110. As shown in the view of FIG. 2, the control contour 202 is formed by a groove extending in the working ring. The grooves are removed from the surface of the actuating ring 114 oriented toward the locking comb 110 and extend within that depth to the additional surface or lower surface of the actuating ring 114 opposite the surface. Alternatively, the groove may be formed as an indentation in the surface of the working ring, and the lower surface of the working ring 114 is closed. The control contour-groove 202 consists of a first groove section 204 and a second groove section 206, as is clearly shown in the drawing of FIG.

The first groove section 204 is longer than the second groove section 206 and extends closer to the outer contour 208 than the inner contour 210 of the actuating ring 114, Gt; 206 < / RTI > In the shorter second groove section 206, the control contour 202 is curved in a straight line from the curvature point 212 toward the inner contour 210. The first groove section 204 is configured to allow the rotary motion 214 to be rotated in the rotational or rotational motion 214 of the actuating ring 114, corresponding to a characteristic progression in the outer periphery 208 of the actuating ring 114. [ Is configured to be guided in a first position, i.e. outside the blocking contour (200). Due to the characteristic progression of the actuating ring 114 in the direction of the inner periphery 210, the second groove section 206 is located at the second position of rotation of the actuating ring 114 during rotation 214 of the actuating ring 114, Guide the blocking element 112 into the blocking contour 200 arranged in the direction of the center of the locking comb 110 and against the blocking element 112 so that the position is formed and the locking comb 112 is secured Lt; / RTI > The rotational motion 214 and the direction of rotation are indicated by arrows in the drawing of FIG.

The blocking element 112 includes an actuating ring 114 having a face of the blocking element 112 facing the control contour 202 (Not shown). The extension 216 is formed in one piece with the blocking element and is adapted to be coupled by control contour 202, for example, via a shape coupling.

2, the control contour 202 is arranged in the region of the actuating ring 114 forming the control cam 218 of the actuating ring 114 formed as a rounded protrusion. The function of the control cam 218 and the function of the nose 220 formed in the inner contour 210 of the actuating ring 114 is described with reference to Figures 3A-3C below in conjunction with the AutoP function.

2, the device 108 includes a coupling element 222 at the lower end thereof, and the coupling element is coupled to the actuator ring 114 to generate a rotational motion 214 of the actuator ring 114, To the actuating ring (114) for movement of the actuating element (106). The engaging element 222 is configured as a toothed wheel whose main side is fixedly arranged to the actuating ring 114. [ On the free primary side opposite the main side, the coupling element 222 can be connected, for example, with an electric motor, and the torque of the electric motor is transmitted through the coupling element 222 onto the actuating ring 114, Element 106 as shown in FIG.

3A-3C, the main features of the present invention, the shift lock function, and the preferred functional integration of the AutoP function are clearly illustrated.

FIG. 3A shows a perspective view of an embodiment of the transmission 102 of FIG. In the embodiment of the transmission 102 shown in the figure, two functions AutoP and shift lock are integrated.

As described above, in AutoP, the position of the shift knob for the automatic transmission of the vehicle is changed in the manner that the shift lever is rotated back to the position P indirectly from one of the positions D, R, N or the like by the actuator by the actuator. And is synchronized with the automatic parking lock portion. To this end, the transmission 102 according to the present invention is additionally equipped with a locking pin 300, which is additionally spring loaded, in addition to the components already described.

3A, the spring loaded locking pins 300 are arranged radially with respect to the locking comb 110 and are threaded through the locking comb 110 at two diametrically opposed locations . The locking pin 300 is positioned and arranged in the housing of the transmission 102 and the locking pin is configured to be coupled into the locking contour of the locking comb 110 at the first position to secure the locking pin within the locking contour do. In this position, the locking comb 110 can only be moved through the locking pin 300, i.e., harder. In the second position, the locking pin 300 moves out of the locking contour to release the locking comb 110 for a flexible, free rotational movement.

The locking pin 300 is connected to a spring element of the apparatus 108, not shown in the view of Figure 3A, and the spring element is used to retain the locking pin 112 in the first position or to move the locking pin using an elastic force . The control cam 218 already mentioned is formed through the radial extension of the actuating ring 114, which is larger than in the remaining area of the actuating ring 114, and the control cam, in response to the rotation of the actuating ring 114 , And to move the locking pin 300 from the first position to the second position against the resilient force. In the functional state shown in FIG. 3A, rotation 302 of the actuating ring 114, indicated by the arrow, is performed for disengaging the locking pin 300 and the locking comb 110. The state diagram of the return position of Figure 3A shows that the control cam 218 receives the locking pin 300 through the extension of the locking pin 300 upon rotation of the actuating ring 114 and causes the locking comb 110 to rotate And the control cam is moved to the second position to be released.

According to the AutoP-function, in the return position shown in Fig. 3A, the locking cam 110 is rotated in the direction of the arrow X1, which is offset from the control cam 218 and through the nose (not shown) arranged in the actuating ring 114, A stop element (not shown in the figure) is interlocked with the rotation. A shift lever or rotary knob 106 that is rotatably supported and is directly connected to the locking portion is rotatable by an electric motor connected to the actuating ring 114 via the engaging element 222, including the locking portion 110, And is indirectly returned and rotated, thereby synchronizing with the parking lock of the transmission.

The blocking pin or blocking element 112 is deactivated in the functional state shown in FIG. 3A, i.e., because the locking comb 110 can be interlocked at rotation 302 of the actuating ring 114 in the AutoP- Lt; RTI ID = 0.0 > 200 < / RTI >

3B and 3C, the shift lock function of the shift device 102 will be described precisely.

Referring to another perspective view of Fig. 3B, the intermediate position of the transmission 102 of Fig. 3A is shown. The first section of rotation 304 of the actuating ring 114 indicated by the arrow is performed in the opposite direction as shown in Fig.

3B, the control cam 218 releases the locking pin 300 that is coupled again by an elastic force and secures the locking comb 110. As shown in Fig. The blocking element 112 is guided within the first groove section 204 of the control contour 202 in the first section of rotation 304. Correspondingly, the blocking element 112 is placed in a first position, i.e., outside the blocking contour 200, and is thereby inactive. When the vehicle brakes are active while P or N is not set in the shift knob 106 or the shift knob 106 is set to P or N, the shift device 102 shifts to the shift lock function shown in Fig. As shown in Fig. In this state, the shift lock is inactive and the driver is able to operate the operating element 106.

3C shows a state diagram of the blocking position of the shift lock function of the transmission 102 at the end of the rotation 304 in another perspective view. The blocking element 112 is guided in the second groove section 206 of the control contour 202. Correspondingly, the blocking element 112 is located in the second position and is coupled into the blocking contour 200. As a result, the blocking element 112 is activated and locks the locking comb 110. Shift lock is active in the shifting state of the transmission 102 shown in Fig. 3C; The operating element 106 can not be moved to another position, for example because the transmission is in the parked or neutral position and the vehicle brakes are inactive. The locking pin 300 is still engaged.

When the driver operates the vehicle brake from the state of the transmission 102 shown in Fig. 3C, the actuators (not shown) connected to the actuating ring 114 via the coupling element 222, Leading to the return rotation 306 of the actuating ring 114, indicated by the arrows in the figure, until the guidance is again performed by the first groove section 204. [ Thus, the blocking element 112 again moves out of the blocking contour 200 and releases the locking comb 110 for rotational movement. The driver can now operate the operating element 106 and set the desired gear stage.

The functional integration shown with reference to Figs. 3A and 3C enables shift operation with a shift lock function without requiring additional actuators. To this end, an additional control contour 202 is provided in the return ring 114 already present in the AutoP-function. Through this control contour 202, the blocking element 112, which is positioned and arranged in the housing of the transmission 102, is moved. Thereby, the shift lever 106 is locked or unlocked in the position P, N. In this case, the provided actuator performs the rotation of the return ring 114.

In summary, the function flow of the shift lock function in P and N shown again with reference to Figs. 3A to 3C will be described. In AutoP, first, the disengagement of the locking pin 300 and the locking portion 110 is performed. At the time of the continuation rotation 302 of the return ring 114, the locking portion 110 is interlocked with the engagement point and is returned to P and rotated. After the shift lever 106 reaches the P position, the return ring 114 is returned to the starting position by the rotation 304 in the opposite direction. In this case, the locking pin 300 is again engaged with the locking portion 110.

When a "shift lock input" is required, the return ring 114 continues to rotate in the opposite direction of rotation 304 in the AutoP direction, thereby moving the blocking element 112 through the control contour 202. Thereby, the shift lever or the rotary knob 106 is blocked.

When "shift lock input release" is requested, the return ring 114 is returned to the start position by rotation 306 and rotated. The blocking element 112 is moved through the control contour 202 and the shift lever 106 is unlocked.

Figs. 4 and 5 show a detailed view of a rotary transmission 102 according to the present invention having a shift lock function using a disengaged locking portion 110 and a blocking element 112. Fig.

4 is a perspective view of a transmission device 102 having an unlocked operating element 106 according to an embodiment of the present invention.

An apparatus that is operated using the method 600 may be the apparatus described with reference to the drawings, which may be coupled to or coupled to an operating element of an automatic transmission of a vehicle, A locking comb, a blocking element for locking or unlocking the operating element, and an operating ring having a control contour rotatably supported for guiding the blocking element.

The method may be executed by a control device of the vehicle associated with the device.

In step 602, the control ring is used to move the blocking element from the first position to the second position, to lock the locking comb, and in order to lock the operating element, the actuating ring is moved And is rotated in the first rotation direction. The operating element can no longer be moved by the operator. In step 604, to actuate the blocking element from the second position to the first position using the control contour, and to release the locking comb for rotational movement of the actuating element associated with the locking comb, Which is the opposite direction to the direction of rotation. Thereby, the operating element can be unblocked and moved by the operator.

Through steps 602 and 604, the assignments for "shift lock input" and "shift lock input release"

For example, in another optional step that may be performed prior to steps 602 and 604, AutoP-functionality may be implemented. To this end, in order to block the coupling of the locking pin into the locking comb, and then to block the locking comb, the actuating ring may first be rotated in the second rotational direction without the locking of the locking comb needing to be overcome. The operating element is rotated to reach the parking position. The actuating ring can then be rotated in the first rotational direction such that the locking pin is again engaged with the locking comb. The operator can actuate the actuating element again by locking the locking comb. For the input of the shift lock, step 602 may be executed.

Further, in the drawings, when the operating element is already shown in combination with the apparatus for blocking the operating element, an apparatus for blocking the operating element can be provided without the operating element. The operating element can be assembled to the device at a later time, for example.

When the above-described element is configured to enable the function, the element is preferably configured and / or arranged to enable the function.
